The Wii U has options to play DS games with the screens flipped any way you want them if you got one, only caveat being you either need the Virtual Console releases or you can make your own VC injects for free using Nintendo's official emulator
Good thing the Wii U is easily hacked

We are soldiers without borders, our purpose defined by the Era we live in; we will sometimes have to sell ourselves and services. If the times demand it, we'll be revolutionaries, criminals, terrorists.
And yes, we may all be headed straight to Hell, but what better place for us than this? It is our only home.
Our Heaven, and our Hell.
This, is Outer Heaven.
